PERT Diagramm cannot be printed or exported

Hello,

I cannot export my PERT Diagramm… Is that normal, or is there anything specific to do?
The print option is not working either, I just have the possibility to print the tasks and the GANTT planning…
Thanks for your kind help,

Corinne

Thanks, I will take a look.
